Power Cells are special items in Horizon Zero Dawn. Power Cells can be collected from a number of locations across the world to be used for the side quest Ancient Armory.
Power Cells also appear as a quest item in Heap of Trouble and Waterlogged, though these are separate from the items collected for Ancient Armory.
